O'Malley serves as Boston's District 6 City Councilor and represents West Roxbury, Jamaica Plain and parts of Roxbury, Roslindale and Mission Hill. On Monday, he said Healey would prove to be a strong presence as Attorney General.
"Maura Healey has fought for Bostonians, ensured access to women's health care and brought suit against banks that sold bad mortgages in our neighborhoods," O'Malley said in a statement. "She will lead the fight to reduce gun violence, tackle drug addition and empower our most vulnerable residents. Maura is a powerful advocate, a civil rights attorney and a compelling progressive leader. I am proud to endorse her campaign for Attorney General."
Healey has also received support from Northwestern District Attorney David Sullivan, State Police Colonal Marian McGovern, former U.S. Sen. William "Mo" Cowan and a number of other officials across the Commonwealth.
"I'm so honored to have Councilor Matt O'Malley's support," Healey said in a statement. "Since taking office, Matt has devoted himself to making Boston a better place to live and work in. He is an advocate for the city's children, families, business owners and public safety officials. I'm thrilled to have Matt on my side and I look forward to working with him."
